Animated/rotoscoping mask FCPX?

Is it any plugin/effect or tool in FCPx for rotoscoping or
an easy 4-8 mask where its possible to animate each mask point.

alex4d 8point is the mask I am usin for the moment it works semi good.

But I want to keyframe each point in the mask. In alex4d you can only keyframe place and proportion of the mask (if i haven't missed some thing).

Of cours i could send the clip to Motion 5 but that will kreat a mutch more complicated workflow.
